In his plea, Schuster admitted the crime occurred from April 2007 to August 2012 while he was doing business as Manhattan Pain and Spine at 1135 Westport Drive in Manhattan. To carry out daily operations at his clinic, he employed up to 12 office staff members at a time, none of whom had lawful authority to distribute controlled substances. He directed and allowed staff members to distribute controlled substances to his patients using blank prescription pads he had signed in advance.

Investigators documented approximately 540 patients who received prescriptions for controlled substances while Schuster was out of his office, including times when he was traveling to Canada, Russia, South Africa, Uruguay, New York, Argentina, Chile, Paraguay, Brazil, and Israel.

In addition to the prison sentence, Schuster agreed to pay restitution of $100,772 and a fine of $25,000. He also has agreed to forfeit his clinic building at 1135 Westport Drive, a 2012 Ford pickup, and more than $11,000 contained in two bank accounts. He also agreed to a forfeiture money judgment of $400,000.

Furthermore, Schuster agreed to surrender his medical license, not to re-apply for a medical license in Kansas, to surrender his DEA registration number for prescribing controlled substances, and not to re-apply for a DEA registration number.

According to court documents, the investigation began early in 2012 when the Riley County Police Department received reports that Schuster was issuing prescriptions for high dosages of scheduled drugs based on minimal or cursory physical examinations.

Grissom commended the Riley County Police Department; the FBI; the Department of Defense, Criminal Investigative Service (DCIS); the Department of Health and Human Services, Office of Inspector General (HHS-OIG); the Drug Enforcement Administration (DEA); the Department of Homeland Security-Homeland Security Investigations (DHS-HSI); the Diplomatic Security Service (DSS); Assistant U.S. Attorney Tanya Treadway; Assistant U.S. Attorney Jared Maag; and Special Assistant U.S. Attorney Robin Graham for their work on the case.
